Now I decided to make 4layer PCB for ep2c20f256 ep2c8f256 and ep2c5f256 insted of 8layer PCB for ep2c20;35;50 in FBGA484 package becose its to expensive and I dont now how big device I will need, so a good starting point would be ep2c20 in smaler FBGA 256 package.

As I already have routed in 2 layers ep2c20f256 device then i will need to add ground planes and VCC INT,i/o plane.

How much layers these small FPGAs need 4 or 6 ?

If I will need in future larger device then I will make PCB for FBGA672 package becose it covers larger devices than FBGA484.

Wen I will route mu nev 4 layer or 6 layer PCB the I will post link to pictures.
